I believe it's a matter of priority as to how Woopra compares to Google Analytics.
If you are OK with Google compiling all of your statistics into a huge database along with everyone else in the universe because a zero cost service is the most important thing, you will not likely be pleased with Woopra's pricing model when we release it.
However, if you are willing to pay a little in order to truly understand the individual behaviors of your specific visitors (by individual user login), to be able to communicate and interact with them, to keep your information private and firewalled from others, and to do all of this in real time, then Woopra may be right for you.
Since we launched the beta we've been 100% clear that Woopra was never intended to be free for all users. We want it to be as low cost as possible, but frankly there is no reason that a heavily trafficed site shouldn't be able to contribute a little to help offset the infrastructure and manpower required to provide the most useful stats out there. Sites with heavy traffic usually have ads, or are of a commercial nature. So a small fee shouldn't be an issue.
As far as Google's reports being more powerful, I completely disagree. Google can't even tell me WHO visited my site. And they can't do it in real time. Having said that, if there are any particular views of the statistical data that you want to see we can easily add them to Woopra, because we're collecting the data anyway. Just drop a note on the feature request board and we'll get it baked in.
Finally, I'm not sure what type of problem you are experiencing, but when I take a look at the back end it appears that you are able to get hours and hours of data on your higher traffic sites and all of the traffic on the others within the 10k limit. If you are having problems with this please drop us a line via the Contact form, or post a bug on the other forum so we can get you sorted out.
Thanks,
